Filed: 1926-01-29
Abstract: 246,864. Budd Manufacturing Co., E. G., (Assignees of Ledwinka, J.). Jan. 29, 1925, [Convention date]. Latches, sliding .-To enable the sliding window-frames in doors of motor vehicles to be as wide as possible, the operating means of the door latches are connected bv mechanism which extends downwardly beneath the window-pane in its lowest position. A latch bolt 12 mounted on the inner side of the window-pane 76 is operated from inside by a lever 28, one end of which forms the handle, and from the outside by a handle 47 having a follower 44, Fig. 4, on its spindle which raises a plate 41, connected, through strips 69, 63, with a bellcrank lever 67 which acts on a projection 26 on the bolt. The strip 69 may be flexible, but the strip 63 is stiffened, and both connected at their ends by a pivot 84 and guided in a bracket 70 mounted in the door below the window-pane. A pin-and-slot connection 65, 66 between the strip 63 and bellcrank 67 allows independent action of either operating means. The outside operating means is mounted close to the window-pane and as near the inside of the door as possible so that the strip 69 may extend vertically behind the inwardly curving outer surface of the door. Springs 30 and 48 return the parts to their initial position after operation and a spring 72 on the rivet 74 prevents rattle. Instead of the lever 28, a handle on a vertical rotating spindle with a projection directly engaging the bolt may be used, and a rattling-preventing spring may be employed at the pin-and-slot connection.

Title: Improvements in or relating to wheatstone bridges
Inventor: HARDING GEORGE NELSON
IPC: G01R17/10
Filed: 1949-01-31
Abstract: 660,470. Bridge circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 31, 1950 [Jan. 31, 1949], No. 2679/49. Class 37. A bridge comprises two fixed resistance arms 13, 14 in series between two D.C. supply points 11, 12 and two further resistance arms 17, 18 which are in series between the same points and are adjusted in accordance with two variables, the ratio between which is to be indicated by a meter 19. The resistance of the meter circuit, which may include a series resistance 20, is high compared with the maximum resistance of either adjustable resistance arm 17, 18 in order to limit the response of the meter when the resistances 19, 18 are reduced without varying their ratio. A resistance 21 less in value than the overall resistance of the bridge between the supply points 11, 12 when both adjustable arms 17, 18 are at their minimum value is included in the supply circuit. Fixed resistances 15, 16 are included in series with the variable resistances 17, 18 and are of such value that the minimum value of each adjustable arm is greater than that of the corresponding fixed resistance arm 13, 14. The bridge may be supplied from a 12-volt accumulator, suitable values for the resistances 13, 14 being 10 ohms each, the resistance 21 being 3 ohms, the resistances 15, 16 being 20 ohms each, and the resistances 17, 18 being each variable between zero and 3980 ohms. The meter 19 may be of the moving-coil type having a resistance of 80,000 ohms, which may be provided in part by the resistance 20. In order to compensate the meter 19 for any variation in supply voltage the moving system may be acted on by an electromagnet connected across the supply points 11, 12, as shown at 22, 23, so that the control torque is also dependent on the supply voltage.

Title: Improvements in automatic tire vulcanizing mold
IPC: B29C43/10
Filed: 1931-01-28
Abstract: 371,065. Vulcanizing tyres. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Boyden, R. W. and Dana, C. A. ; Receivers of Fisk Rubber Co., Chicopee Falls, Massachusetts, U.S.A.) Jan. 28, 1931, No. 2808. [Class 70.] A vulcanizing press comprises a stationary steam-heated mould member, towards and from which a second mould member is moved by toggle linkage, with automatic means for opening the press after a predetermined interval. The timing means also controls admission of a pressure medium to the interior of the tyre, and its release therefrom. The upper mould 40 is mounted in a steam chamber 23 carried by rods 24 bolted to the baseplate. The mould 40, Fig. 4, is held in position by a steam-heated head-ring 42 attached to the chamber 23 by bolts 55, and also by bolts 53 with heads partly cut away, so that half a turn releases them. The lower mould member comprises a steam chamber 31 on a swinging arm 32, and manipulated by toggle links 35 operated by a hydraulic ram 33. The chamber 31 carries a mould 41 and head-ring 43 which is bolted to a frame 48 mounted on parallel links 49 mounted on the frame. On opening the mould a stop 51 on the frame 48 comes into contact with a projection 52 and prevents further downward movement of the head-ring 43, and so assists in removing the tyre from the mould, and facilitates the placing in position of a fresh. tyre. The timing device consists of a ratchet wheel operated by a pawl on an eccentric constantly driven by an electromotor. The ratchet wheel 83, Fig. 1, rotates a shaft carrying cams operating valves controlling the supply of compressed air and hot water to the apparatus. On pulling an adjustable rod 103 the cam shaft is partly rotated, admitting pressure to the back of the cylinder 33, to close the mould, and also withdrawing one of two pins holding the pawl clear of the ratchet wheel. As the mould closes, it withdraws the second pin, and allows the pawl to engage the ratchet wheel, and the driving of the cam shaft to commence. At the same time a projection 151 on the arm 35 opens a valve to admit hot water to the interior of the tyre. As the cams rotate they operate valves successively to drain the tyre, open the mould, and to withdraw the pawl from engagement with the ratchet wheel. Independent safety-valves are provided to prevent the opening of the mould while there is any pressure in the tyre.

Abstract: 1,108,605. Temperature alarms. INTERNATIONAL RESEARCH DEVELOPMENT CO. Ltd. 18 Jan., 1966 [25 Jan., 1965], No. 3242/65. Heading G4N. [Also in Division G1] A positive temperature coefficient resistor or a series thereof, 1, 2, 3, 4, 5, Fig. 5, is supplied with a constant current from a source 6, and when one or more of the resistors undergoes a sharp increase in resistivity due to thermal runaway upon attainment of a particular temperature, a voltage sensing circuit, responsive to rate of change of voltage across the resistor or the series of resistors, operates an indicator and alarm. The voltage sensing circuit is connected at 7, 8 across the series of resistors 1, 2, 3, 4, 5 and the resistor which has abruptly increased in value is identified by arranging a voltage limiting device such as a Zener diode across each resistor, each diode defining a different limiting voltage, and noting the magnitude of the increase in voltage registered by the indicator. The fact that the alarm is operated by a rate of change of voltage ensures that it is not erroneously operated by large but slowly occurring changes in indicated voltage arising from small changes in all the resistors due to slight variations in ambient temperature.

Title: A device for controlling the supply of a liquid
IPC: G05D11/00
Filed: 1954-02-03
Abstract: 740,672. Proportionate mixing of fluids in flow. KALLE, K. T. Feb. 3, 1954, No. 3253/54. Class 86. [Also in Groups XXVI and XXIX] Apparatus for controlling the supply of a liquid (e.g. the supply in a predetermined ratio of a dye to a fluid medium in flow) comprises a rotary pump having an inlet for the liquid and an inlet for gas, an outlet with a restricted passage for the mixture of liquid and gas, a discharge pressure actuated valve controlling the supply of the gas, and a supply of compressed gas also for controlling the valve. In the form described liquid is supplied to the vessel 16 by the pipe 31 and leaves by the pipe 30. The rotary pump 1 pumps another liquid from container 3 through pipes 2 and 18 into the vessel 16. The restriction 17 causes a back pressure to be set up in the pump and this pressure is transmitted by the pipe 19 to the Bourdon tube 21 which tends to straighten and open the valve 23, allowing air (or gas) to be sucked through the flexible pipe 5 and the pipe 4 into the pump together with the liquid, causing the back pressure to decrease and the valve 23 to close. When the valve 23 reaches an equilibrium position and the discharge of liquid from the pump is steady, this equilibrium position, and so the discharge of liquid, can be adjusted by means of the screw 28. A source of compressed gas at constant pressure is connected to the pipe 8a and by means of the fine bore pipe 15 the gas escapes below the surface of the liquid in the vessel 16. The rate of flow out of the pipe 30 increases as the level of the liquid in the vessel 16 rises so increasing the pressure in the pipes 15, 8, the restriction 13 preventing the pressure of the supply of gas being affected, and the Bourdon tube 7 tends to straighten so lowering the valve seat 6 and throttling to air supply, the liquid discharge of pump 1 increases and by adjusting the screw 12 the rate of liquid discharged by pump 1 can be made proportional to the head of liquid in the vessel 16.
